Sweetie size 8 is small. I will never be a size 8. The average American woman is a size 14. If you're not comfy with your body, that's one thing. But you need to examine your motives for your discomfort. Do you see your own body realistically? Do you allow him (or others) to badly influence how you feel about your own body?

Losing weight is for you. For your health, for how you feel about your body. If he is pleased with your new body, that's great, but it's not for him. If you lose it for him, it won't stay off, unless it's out of fear. You don't want that!
